Replacing the System Module

007-4486-001
If you are instructed by your service provider to replace the system module, you must
follow these steps:
Note: You must remove the PCI tray, because the printed circuit board beneath it
contains a host chip with important information such as the workstation's serial number.
1. Remove the power cable, and remove the system module from the chassis. See
"Removing the System Module" in Chapter 2 and "Reinstalling the System
Module" in Chapter 2.
2. Remove all of the DIMM modules from the system module that you are returning
and reinstall them on the replacement system module. See "Removing Memory
Modules" in Chapter 2 and "Installing Memory Modules" in Chapter 2.
3. Remove the PCI tray from the system module that you are returning, and reinstall it
on the replacement system module, as follows. If a PCI board is installed in the tray, do
not remove it from the tray.
• If you have an RM7000class workstations, see "Removing a PCI Board in an
RM7000class Workstation" in Chapter 2 and "Installing a PCI Board in an
RM7000class Workstation" in Chapter 2.
• If you have an R12000class workstations, see "Removing the PCI Tray in an
R12000class Workstation" in Chapter 2 and "Installing a PCI Board in an
R12000class Workstation" in Chapter 2.
4. Remove the CPU module from the system module that you are returning, and
reinstall it on the replacement system module, as follows:
• If you have an RM7000class workstation, see "Replacing the RM7000class CPU
Module."
• If you have an R12000class workstation, see "Replacing the R12000class CPU
Module."
5. Remove the digital display adapter board, if one is installed, and reinstall it on the
replacement system module. See "Removing an Option Board" in Chapter 2 and
"Installing an Option Board" in Chapter 2.
6. Ship the stripped-down system module back to SGI in the container that held the
new system module.
